For the phase-2 project at the Julong Copper Mine on the Qinghai-Tibet Plateau, at an altitude of roughly 5,300 m, ETENZ completed the enclosure-shell manufacturing and interface provisioning of an ultra-long high-voltage variable-frequency-drive (VFD) E-House, giving TMEIC's HV VFD equipment a prefabricated enclosure platform that can be inspected, transported, and positioned ahead of time.
ETENZ has delivered an ultra-long high-voltage variable-frequency-drive (VFD) enclosure shell for the high-altitude mining district of the Julong Copper Mine. Sitting on the Qinghai-Tibet Plateau, Julong is one of China's largest copper mines; as its phase-2 expansion advanced, the site needed to deploy high-power VFD equipment in the field under demanding conditions: an altitude of about 5,300 m, continuous power-distribution operation, and the packaged delivery of large equipment.
The high-voltage VFD equipment for the project is supplied by TMEIC, and ETENZ manufactured and delivered the prefabricated enclosure shell that houses it. Working to the equipment layout, maintenance access, and on-site installation boundary, ETENZ completed the structural forming and interface reservations of the ultra-long enclosure in the factory, so the equipment could be positioned quickly at the high-altitude site.
A high-altitude mining site places higher demands on enclosure sealing, protection, ventilation and cooling, and maintenance access. During shell manufacturing, ETENZ advanced the structural and interface fit to the equipment drawings and installation boundary, establishing a stable basis for moving the VFD units into the enclosure and installing them on site.
To house rows of VFD and control cabinets, the enclosure adopts an ultra-long structure, formed as a single piece of about 36 m. ETENZ completed the shell around the cabinet layout, maintenance clearances, door operation, and air-duct openings, so the structure, installation interfaces, and service access match the integration needs of the equipment.
High-power VFD operation generates concentrated heat, so the enclosure reserves interfaces for fans, air conditioning, fire protection, lighting, and emergency maintenance. ETENZ planned these interfaces together during shell manufacturing, reducing rework and on-site coordination after the equipment is moved in.
Shell prefabrication, exterior forming, interface verification, and loading for delivery are concentrated at the factory, moving more preparation ahead of on-site installation. This suits engineering environments like high-altitude mining sites, where work windows are limited and coordination costs are high.
The project sets a delivery benchmark for ultra-long VFD enclosure shells serving large high-altitude mines. ETENZ completed the overall coordination of enclosure structure, exterior, interfaces, and maintenance access at the factory, providing a reliable enclosure platform for the on-site integration and delivery of high-voltage VFD equipment. The technical design, system performance, and on-site commissioning of the VFD units themselves remain the responsibility of the equipment supplier and project parties within their contractual scope.
